Pyrethrins are botanicals derived from which plant?

• A. Chrysanthemum flowers
• B. Dandelions
• C. Tulips
• D. Sunflowers

Answer: (A)

Pyrethrins are natural insecticides derived from chrysanthemum flowers. Specifically, they come from the flower heads of certain Chrysanthemum species, such as Chrysanthemum cinerariifolium and Chrysanthemum coccineum. The compounds work by disrupting the nervous system of insects, affecting sodium channels and causing rapid paralysis and death after contact or ingestion. This botanical origin is what sets pyrethrins apart from synthetic insecticides. The other plants listed—dandelions, tulips, and sunflowers—are not sources of pyrethrins, so they’re not the origin of these botanicals.
